Panasonic IP surveillance solutions installed at the National Archives protect 900 years of UK history
The National Archives has installed a total of 58 static cameras and 41 PTZ cameras from Panasonic
The National Archives, based in Kew, London, houses 900 years of UK history. From the Doomsday Book to present documents, it has records ranging from parchment and paper scrolls through to recently created digital files.

The National Archive building has recently undergone a change, with the family records centre moving from Islington into its premises to create the largest collection of UK historical documents in the country. With this change came the need for an improved security system to protect the thousands of priceless documents. Security and Operations Manager, Jack Lincoln, prepared a non-technical spec for the requirements of the new system and put it to tender.

Objectives

Where historical records of government are released into the public domain, the National Archives then provides a function to provide access to the documents by the public. Once a member of the public has gone through its registration process as a reader, then they are entitled to have that access to any document they need. If a document has an element of damage to it and requires special care then there is an invigilation room where Lincoln and his team pay even closer attention to how the documents are handled. The ethos of the National Archives is to maintain documents for future generations as well as existing generations. The Archives therefore needed a security system comprehensive enough to be able to effectively manage the use of the documents.

Lincoln explains: "The required system was dedicated to public access and solely operated through the public opening hours. The general building and external areas are operated by a different control room and kept very separate as they are two very different functions." West London Security headed by George Rohan won the tender based on their interpretation of the non-technical spec through specifying a complete end-to-end Panasonic surveillance system with a total of 58 static cameras and 41 Pan Tilt Zoom (PTZ cameras).

The solution

Most of the cameras were required within the reading rooms mounted above reading tables and camera stands where the public can photograph their own copies of documents. The Panasonic CCTV cameras are mounted directly above the stands so that what's happening with the document can be clearly seen. George Rohan explains: "The Archives had experienced issues in the past with the handling of the documents and has a much smaller surveillance system; therefore they were more reliant on staff walking around undertaking invigilation to keep an eye on the documents. Due to the major refurbishment that took place as a result of the family record centre moving from Islington into the building, it meant we could specify a brand new system that could watch over the documents much more efficiently than the previous system or from just a passing member of the security team."

Lincoln takes up the story: "The old system relied solely on PTZ cameras. This time round with WLS we looked at a system that had coverage with fixed cameras supporting the PTZ cameras. This combination of fixed and PTZ gives us a close view of the table using PTZ whilst the fixed cameras provide a view of three tables per camera. So it gives us a general view of what's happening with the ability to bring the PTZ into play if we see something we are a bit concerned about."

For the installation of the Panasonic system a shut down period of one and a half weeks over Christmas was utilised in which all cabling was installed. Rohan explains: "The first step was to cable all 99 cameras. However it was impossible to get all of the cameras installed at the same time so it was completed in two stages, with the old camera system and new system working together at the crossover stage to ensure Jack and his team were never without coverage of the documents."

Quality images for effective surveillance

When the family record centre moved, there was the need for a redeployment of staff including security. Additional security staff was required elsewhere which meant the redeployment of their existing numbers as opposed to recruiting staff. Lincoln explains: "We still have staff within the reading room undertaking invigilation but they are smaller in number than in the past. We have radio contact with them and if we see something happening on camera, we are in a position to alert that member of staff to go and deal with the issue that was identified. This new security system has given us an excellent tool to undertaken invigilation within the reading room."

Lincoln and his team were extremely impressed with the quality of the images and of the zoom lens on the PTZ, which makes the invigilation of the documents much easier. Lincoln continues: "With the overhead PTZ you can almost read the text of the document that is being used. We are not just looking for malicious damage of the documents, we are also looking too make sure the documents are being supported correctly with appropriate tools we provide. The cameras are used for document handling as well as criminal damage. If a document is seen to be mishandled, one of the invigilation officers would go and give advice to explain how it should be handled."

"This allows us greater coverage and knowledge into what is happening in the reading room and has allowed us to pick up issues that perhaps in the past wouldn't have been picked up. The Panasonic cameras give us a better tool to deal with issues. We had an issue where a student was underlining in pencil on the original document whilst undertaking research, but this could have caused major damage to the document if it hadn't been picked up on the cameras in time. In which case it has to go to our collection care department to be restored which is an expensive process."

"The documents' value varies to priceless, but the value of the document doesn't determine what level of access is given as we, as a function, don't put a monetary value on them - they are there to be used by the public and treated as normal documents. It's our job using the new system to control and minimise any damage."

Modern surveillance solutions from Panasonic help to protect old documents at the National Archives

An additional benefit of the Panasonic system is the visibility of the cameras, although the Archive has rarely experienced theft, cameras are deliberately on show to perform a deterrent value as well as an operational value.

Operational requirements

The control room is only manned during the opening hours of the reading rooms, therefore recording capacity needed to match these requirements. WSL were provided with an empty room to install the cables and racks containing the Panasonic WJ-RT416 digital video recorders (DVRs). The WJ-RT416V encompasses high quality and high compression for economical longer recording. The MPEG-4 compression method enables smooth recording of moving objects allowing system supervisor the ability to play-back footage without loss of picture quality. WLS specified the system to record at the highest rate of 25fps during opening hours and 25fps set on motion detection out of hours with storage duration of 31days. Jack Lincoln explains why the recording period is so important: "The footage is kept for 31 days because we might have a document that is discovered to be damaged after the event, so we need to be able to go back and look at that. If you think of the amount of documents we house, at last count it was about 3.5 million, and the amount of public viewing those documents, there could be damage to it when it is handed back as we can't check every document."

For the design of the rack room George Rohan incorporated both the Archives' current and future needs: "Our idea was to install two big racks in the middle of the room as it's vital to keep the kit cool and separated this from all the cameras. Positioned in the middle of the room we used the mini ducks in the ceiling to allow us to cable down from the ceiling. We also made sure that there was enough space in the room to add additional recorders and another rack if the Archives were ever to increase the recording capacity to six months storage, therefore all storage is kept in the same area."

Additionally the system is backed up by UPS which WLS saw as a necessity due to the area regularly experiencing spikes in the power and thus they needed to make provisions for these instances so that no data was lost. In the dedicated control room Jack Lincoln and his team utilise 4 x 42" plasmas and 4 x 20" LCD monitors controlled via two WJ-CU650 Panasonic joystick keyboard controllers. Lincoln concludes: "Overall it's a very pleasing situation. From the non-technical specification which I presented to West London Security of what I wanted to achieve, this turned into the actual technical specification by George and his team in putting this together and we now have a very effective tool here for invigilating and keeping the documents safe."

4K analogue cameras are still an ideal solution for video surveillance systems
4K analogue cameras are still an ideal solution for video surveillance systems

One of the toughest business decisions companies need to make is when selecting a new video surveillance system, as it’s a rigorous process to compare camera offerings and technologies, and to evaluate price structures. With its proven performance over the last several years, IP surveillance systems have become the defacto standard for most professionals. Those experts typically cite the numerous benefits that IP cameras offer, including higher image resolution, ease of installation, scalability, and analytics as rationale – which are all valid. However, the biggest drawback is the high price tag when considering making the switch from an analogue to a dedicated IP surveillance system. In reality, many end users don’t need networked IP cameras in every location throughout their facility, as the additional features and benefits IP cameras typically provide may not be necessary in every location. Ultimately, the decision to stick with analogue or move to IP needs to be based on your surveillance objectives and future needs. Advantages of 4K Consider this – you’re managing an analogue surveillance system and your primary goal is to increase image resolution; 4K analogue cameras may be your ideal solution. Advanced 4K analogue surveillance cameras deliver a myriad of advantages, including: Superior resolution Lower cost and easy installation. Picture clarity even under changing or difficult lighting conditions Models with 2 and 4 megapixel resolution, such as Dahua’s HDCVI 4K cameras with scalable HD-over-coax technology, provide security professionals with greater situational awareness and are available in multiple form factors to provide exceptional quality video & audio for a wide range of surveillance applications.Since 4K analogue cameras are not connected to an IP network, they do not present the cybersecurity risks that are typically associated with IP cameras Greater distance, greater definition Another benefit of 4K analogue cameras is that their higher number of pixels provides increased digital zoom performance without pixilation versus traditional HD or 2K cameras. This allows security operators to see further into the distance with greater definition. The added resolution is especially important for popular applications that require higher levels of detail, such as face and licence plate recognition or object analysis, as well as emerging video analytics and artificial intelligence applications for future system enhancements. 4K analogue applications 4K analogue cameras are also ideally suited to cover large fields of view such as in sports stadiums or airports with great detail and accurate colour reproduction. Their superior digital zoom capabilities can allow 4K analogue cameras to do the work of two cameras – one for a wide view and another for close-up – without sacrificing quality or compromising security. This can also help dramatically reduce hardware and installation cost, and simplify video monitoring. Finally, since 4K analogue cameras are not connected to an IP network, they do not present the cybersecurity risks that are typically associated with IP cameras. With the ever-increasing amount of sensitive and personal information stored on networked drives at businesses of all types, the value of removing one more potential network entry point cannot be understated. Overall, with 4K analogue cameras, security professionals can take advantage of higher resolution video on an existing, cost-effective platform that’s safe from network intruders with isolated and limited installation downtime and exceptional cost-efficiencies.

How new video surveillance technology boosts airport security and operations
How new video surveillance technology boosts airport security and operations

The air travel industry has evolved from one commercial passenger on the first commercial flight in 1914 to an estimated 100,000 flights per day. According to The International Air Transport Association (IATA), the total number of passengers who flew in 2017 is expected to reach 3.7 billion.   But it’s not just people who fly. Each day, more than $18.6 billion of goods travel by air, which represents one-third of all world trade, by value. Meanwhile, the aviation industry supports more than 63 million jobs and generates $2.2 trillion in economic activity. According to the IATA, 3.5% of the global economy relies on aviation. Evolving airport security for today’s demands Airport security continues to evolve as well, as security personnel strive to keep ahead of increasing threats and the compliance issues enacted to help address them. It’s taken nearly 40 years to progress from the first widespread use of X-ray scans and metal detectors to today’s full-body imaging and video surveillance solutions to mitigate security breaches and other critical security challenges. Employing airport security solutions is a complex situation with myriad government, state and local rules and regulations that need to be addressed while ensuring the comfort needs of passengers. Airport security is further challenged with improving and increasing operational efficiencies, as budgets are always an issue. As an example, security and operational data must be easily shared with other airport departments and local agencies such as police, customs, emergency response and airport operations to drive a more proactive approach across the organisation. New surveillance technologies To manage these and other issues facing the aviation industry, airport security management is increasingly looking to leverage new surveillance technologies to help streamline operations and to build stronger security programs. New and enhanced surveillance technologies such as powerful open platform Video Management Systems (VMS), HD panoramic cameras, and highly specialised video analytics are at the heart of today’s advanced networked surveillance solutions for airports and aviation facilities. Airport perimeters are quite extensive in size, irregular in shape, and subject to compromised visibility due to poor lighting Protecting the perimeter As an example, many airport perimeters are quite extensive in size, irregular in shape, and subject to compromised visibility due to poor lighting. Compounding the security challenge, these perimeters are often protected only by simple fences that can be easily scaled or broken through, and areas outside the fences may include wild forests in rural areas or residential and commercial buildings in more populous regions. All of these factors make it all the more difficult – and all the more important – to keep watch on perimeter areas. Analytics boosts effectiveness Camera coverage is the first step for monitoring the perimeter, but to improve the monitoring of these areas, airports can automate much of the monitoring, threat identification and notification needed to keep the entire premises safe by implementing video analytics. Market-leading offerings now include cameras with built-in analytic functions to make it easier and more effective to implement improved detection. For example, some of the more commonly available functions now include perimeter crossing, intrusion detection, object left behind, object missing, and wrong direction.Surveillance technologies allow the creation of virtual fences which can send a security team proactive notices of suspicious activity With these functions already built in, today’s high-performance security cameras not only capture clear video but can also employ analytics to monitor the field of view. In the case of an airport perimeter, analytics can be set up to automatically monitor a fence line to detect breaches or potential breaches while filtering out false alarms from small animals or blowing debris and alert authorities quickly when action is needed. Surveillance cameras can also be easily deployed over a perimeter to quickly detect and identify causes of perimeter breaches, and provide instant alerts to notify personnel where the breach is occurring, reducing the need for security personnel to physically monitor miles of perimeter fencing. In fact, surveillance technologies allow the creation of virtual fences which can send a security team proactive notices of suspicious activity. VMS Systems control with confidence All perimeter surveillance solutions can be integrated with an airport’s VMS, providing users with an easy-to-manage centralised hub to monitor and manage airport security. Overall, a perimeter security solution can help keep unauthorised individuals away from runways, taxiways, aircraft and other airport infrastructure in all types of weather conditions and environments. Within other restricted areas of an airport, such as parking lots, garages and secured areas, surveillance solutions are available to reduce risk and improve security. In a parking garage, IP cameras and a VMS can integrate third-party analytics to quickly identify and alert personnel when unauthorised vehicles have entered a restricted area, including vehicles with license plates on watch lists. When an alert is detected, data from third-party vehicle tracking software can be accessed via the VMS to monitor and track the vehicles activity while security personnel get into position to investigate further. Preventing theft in airports On the tarmac and inside baggage handling areas, loss or theft of luggage and other high-ticket items not only cause brand damage to an airport or airline, but complaints from travellers. A CNN analysis of passenger property loss claims filed with the TSA from 2010 to 2014 shows 30,621 claims of missing valuables, mostly packed in checked luggage. The rest occurred at security checkpoints. Total property loss claimed is estimated at $2.5 million. Loss or theft of luggage and other high-ticket items not only cause brand damage to an airport or airline, but complaints from travellers Security technology can mitigate the issue with IP cameras and VMS integrated with a Baggage Handling Systems (BHS) to automatically validate system operation and abnormal behaviours. This allows security and operations management to see where and why alarms are triggered so they can quickly respond and mitigate the problem. Monitoring crowds and foot traffic Inside an airport, VMS solutions with analytics capabilities can monitor crowd movements and anticipate and proactively respond to choke points, crowd patterns and foot traffic flow to reduce risk and improve security. The solutions can quickly and efficiently locate a person of interest, such as a lost child, for example, and search for shirt colour, estimated height to facial features, and more. With the ability to track via recorded and live video, security personnel can start their search from the moment the child was last seen and track their movement throughout the entire airport. Murtala Muhammed Airport Terminal Two (MMA2), Nigeria’s preeminent air terminal, is one example of an airport that is benefitting from a security technology upgrade to mitigate security threats. The airport is using an open platform VideoXpert™ Video Management System (VMS) in addition to a combination of low-light cameras and high-resolution dome cameras to secure its parking structure, perimeter, baggage claim points, cargo area and other parts of the airport.With the ability to track via recorded and live video, security personnel can track a person’s movement throughout the entire airport The security cameras are providing airport security with high-quality images, motion detection, advanced tracking capabilities, and on-board analytics, while the VMS is unifying operational and security data via a single user interface and allowing airport security to be more proactive in its incident response. People counting and ANPR In the U.S., a large cargo airport has employed 1,100 IP video cameras with a new Video Management System (VMS) solution to address the entire airport’s needs, including security and surveillance. The solution not only features crystal clear images, but also can archive video for 30 days at 30 images per second. A VMS manages the system and provides valuable analytics, including people-counting and number plate capture. It will soon add an enterprise security solution to improve access control system management and integration with the VMS. Airports around the world are increasingly realising the benefits of advanced surveillance solutions to drive operational intelligence and provide comprehensive situational awareness. As the transportation industry continues to expand, so will their use of more advanced surveillance systems on the enterprise level that incorporate even higher levels of system control and management, wide area coverage imaging solutions, and intelligence to keep passengers safe and operations running smoothly.

The new alliance of humans and robotics in security solutions in 2018
The new alliance of humans and robotics in security solutions in 2018

  The past year has proved to be a year full of many changes both within our industry and for Robotic Assistance Devices (RAD). While we have experienced increased adoption of artificial intelligence-based solutions, the industry has been challenged with an ever-evolving technology landscape. Protecting enterprise organisations from both cyber and physical security threats will be an ongoing challenge the industry must grapple with. Greater adoption of robotic solutions To address the physical security challenges, we saw a greater adoption of robotic solutions across the board. Our massive industry started to make the change: Shifting from an uneducated view of this advanced technology to increased interest about artificial intelligence across multiple markets including guarding companies, integrators and, most importantly, end-users. In 2017 there was a greater adoption of robotic solutions across the board With security-guard robots, security directors now have access to additional tools to meet their performance and budget goals. Currently, we see a great adoption with progressive guarding companies, which are signing up to have RAD as their robotic guarding partner. RAD deployed its first robot this year, and we look forward to deploying many more as we work with our customers to customise our robotic solution to their needs. Human collaboration with robotics I believe our industry is at the beginning stages of what could be a serious paradigm shift in how we rely on a combination of humans and technology to do a job. We've seen that in video analytics and the wide variety of solutions available on the market today. The trend has progressed beyond video analytics and into robotics, and that will continue to evolve into 2018 and beyond. As we continue to build on the success of our security guard robot solution, we look forward to expanding our product offerings to meet the security needs of our customers.
